The Jacksonville Jaguars have requested permission to interview New York Jets offensive coordinator Brian Schottenheimer, New England Patriots offensive coordinator Bill O'Brien and two other NFL assistants for their head-coaching vacancy, various team and league sources said Monday.

Mularkey went 14-18 in two seasons (2004-05) as the Buffalo Bills' coach. He has been the Falcons' offensive coordinator since 2008, helping mentor quarterback Matt Ryan. That could help his chances in Jacksonville, where the Jaguars are trying to get more out of rookie Blaine Gabbert.
